176 THE MOTHS OF THE BRITISH ISLES. 



Chestnut-coloured Carpet {Thera cognatd). 



This is a generally smaller species than that last referred to, 

 and it is more glossy in appearance. The fore wings are brown, 

 sometimes grey-brown, more or less tinged with reddish, and 

 the basal patch and central band are darker ; these markings 

 are usually white-edged, and there is a wavy whitish sub- 

 marginal line. Hind wings whitish, tinged with smoky grey. 

 Specimens from the Hebrides are strongly purplish ; and Kane 

 states that some he reared from Sligo caterpillars are more 

 richly coloured than any that he has seen from Scotland. 



(Plate 70, Figs. 9 5, 12 ?•) 



The bright green caterpillar is stouter than that of the last 

 species. It is of a bluish hue along the back, and marked with 

 three lines, the central one greenish and the others whitish and 

 broad ; there are sometimes reddish markings low down on 

 the sides, just edging the broad white spiracular line. It 

 feeds in May and June, earlier or later in some seasons, on 

 juniper ; it turns to a dark-green chrysalis in a frail cocoon 

 spun up among the litter under the juniper bushes. 



The moth is to be found in July and August among juniper 

 growing in the hilly and maritime haunts of the species in 

 North England, Wales, Scotland, and Ireland. 



This species, long known as si?nnlaia, Hiibner, has been 

 referred to cog7iata, Thunberg, and as this is an earlier name it 

 will have to be used. 



Pine Carpet {Thcra fir7nata). 



The pale reddish-grey fore wings have a rather darker central 

 band and round-edged basal patch, but the latter is often in- 

 distinct, and the band, which is always deeply indented about 

 the middle of its inner edge, is sometimes not well defined.
